A force of constant magnitude F acts on ...

A force of constant magnitude F acts on a particle moving in a plane such that it is perpendicular to the velocity `vecv(|vecv|=v)` of the body and the force is always direct towards a fixed point. Then the angle turned by the velocity vector of the particle as it covers a distance S is (take mass of the particle as m)

A

`(FS)/(2mv^(2))`

B

`(2FS)/(mv^(2))`

C

`(FS^(2))/(mv)`

D

`(FS)/(mv^(2))`

Text Solution

Verified by Experts

Since `vecFbotvecV` the particle will move along a circle
`thereforeF=(mv^(2))/(R)&theta=(S)/(R)impliestheta=(FS)/(mv^(2))`
